LOS NUEVOS MEDIOS POSEEN CUALIDADES DE PROTECCION DE PLANTAS Y SON APROPIADOS ESPECIALMENTE PARA LA PROTECCION DE PLANTAS CONTRA LA CAIDA DE MICRORGANISMOS COMO HONGOS, BACTERIAS O VIRUS. Compositions containing, as active ingredients, compounds of the formula I in which: X1, X2 and X3 independently of one another are hydrogen, methyl, methoxy, methylthio, halogen or nitro; A is C1-C2-alkyl which is substituted by not more than 3 X-C1-C4-alkyl groups, methyl which is substituted by 2 or 3 halogen atoms, ethyl which is substituted by hydroxyl and/or up to 4 halogen atoms, vinyl which is unsubstituted or carries up to 3 halogen atoms, furthermore ethynyl, propargyl, formyl, acetyl, acetyl which is substituted by not more than 3 halogen atoms, or one of the groups C(R)=N-N(R2)R3, C(N=N-U1)=N-NH-U1, CH(R)-[N(R1)]n-N(R2)R3, C(R)(CN)OR4, C(R)=N(=)nR3, CH(R)-O-N=C(R1)R2, CH(R)-O-N=C(CN)-CONH-R5, C(R6)=N-(O)nR, CH(R)-Y-E-R3, CO-[C(OR)2]nQ, C(Q)=CH-OR or T-Q; in which furthermore: n is zero or 1; X and Y independently of one another are oxygen or sulphur; R and R1 independently of one another are hydrogen or C1-C2-alkyl; R2 is hydrogen, C1-C8-alkyl, C3-C6-alkenyl, C3-C6-alkynyl, C3-C7-cycloalkyl, benzyl or cyano; R3 is hydrogen, C1-C6-alkyl, C3-C6-alkenyl, C3-C6-alkynyl, C3-C7-cycloalkyl, benzyl or an aryl radical U; R4 is hydrogen, C1-C6-alkyl, Si(C1-C6-alkyl)3 or OCOC1-C3-alkyl; R5 is hydrogen or CONHR1; R6 is N(R1)R2, hydrazino or Q; E is CO or SO2; U and U1 independently of one another are a phenyl radical which is unsubstituted or mono- or polysubstituted by identical or different substituents from the series comprising methyl, methoxy, halogen, trifluoromethyl, nitro or cyano; T is C1-C2-alkylene, methylene which is substituted independently of one another by amino, hydroxyl or halogen, or ethenylene which is unsubstituted or substituted by halogen or cyano; and Q is COXR or cyano. The novel compositions have crop-protecting properties and are suitable, in particular, for protecting plants against attack by phytopathogenic microorganisms such as fungi, bacteria and viruses.
